The invention discloses a method for predicting the remaining life of a flight control computer system, which includes using an airborne health monitoring computer to save historical reliability data of the flight control computer, obtaining work status data, and using a fuzzy expert system to perform fault detection of the flight control computer. degree analysis and life prediction. Working status data is obtained from a set of status sensors. The development of the fuzzy expert system is used to model the reliability of the flight control computer system, evaluate the working conditions of the flight control computer system according to the working state data and fuzzy rule reasoning, perform fault detection and predict the remaining life. The advantage of the invention is that the remaining life of the flight control computer system can be estimated online.

The invention provides a device and a method for intelligent terms conversion. The device comprises a DSP central processing chip, a memory module, a display and keyboard operation module and an uplink-downlink communication module, wherein the memory module, the display and keyboard operation module and the uplink-downlink communication module are connected with the DSP central processing modulerespectively, a front-end computer communication module is connected with a front-end computer through a RS-232 bus, a RS-232 communication module is connected with a plurality of sub-stations RTU bya serial expansion circuit, a term converter is arranged between the RTU and the front-end compute of a power communication system, the uploaded communication protocol of the sub-stations RTU are intelligently recognized by a fuzzy expert system, the format of the recognized terms are converted into a unified terms format, uploaded to the front-end computer, and uploaded to each level of workstation by the front-end computer. The invention has the advantages that operators can realize automatic recognition and conversion of terms of interconnected two parties by the device without knowing theterms types of the interconnected two parties, thus avoiding the error possibly brought by manual operation.
